Diaphragm-motor



UNITED STATES PATENT 'OEFIcE CLARENCE lV. BOTJUSS, OF NORVOOD, OHIO.

DIAPHRAGM-MOTOR.

SPECIFICATION forming part of Letters Patent No. 360,651, dated April 5, 1887.

Application filed October 25, 1886. Serial No. 217,193. (No model.)

T0 @ZZ whom, it may concern,.-

Be it known that I, CLARENCE W. BoLUss, a citizen of theUnited States, residing at Norwood, Hamilton county, State of Ohio, have invented a new Diaphragm-Motor, of which the following is a specification.

My invention relates to such mechanism in which,principally,compressed airis used; and the object of my improvement is to gain additional power by passing said fluids through one or more diaphragm-motors, (as, in short,

`I might call my apparatus.) I attain these objects by the construction illustrated in the accompanying drawings, in which- Figure l is a central longitudinal section of the diaphragm-motor. Fig. 2 is a central cross-section of the same.

My diaphraginmotor consists, next, in two segmental shells, 1 1, two flexible diaphragms, 2 2, preferably of leather, a ring, 3, placed loosely between the diaphragms, and means fo rconnecting said diaphragms. In constructing the diaphragm-motor the diapliragms are next cut to the proper size and provided with holes 4 near their outer edges toallow bolts 5 to pass through, and with a central hole, 6, through which a sleeve, 7, having midway a flange, S, passes. The diaphragms .are secured to either side of iiange 8 on sleeve 7 by washers 9 and nuts 10.

Before screwing home thesecond diaphragm a ring, 3, is placed loosely between them. This ring may be solid or hollow, and its diameter is so small in relation to the diaphragms that their outer edges may lap over it so as to almost touch each other. To the outer edge of each diaphragm 2 is secured aseg-I mental shell, 1, by bolts 5,which pass through holes in an annular flange on shell 1, thence through holes 4in the diaphragms, and finally screw into a ring, 11, which takes the place of "a nut to each bolt and clamps the diaphragm myself, however, to this mode of attachment alone. The diaphragm-motor may sit loosely in a cylinder or between guide-rods. Indentations 14 are provided on theinner side of the shells 1 to increase the cubic capacity ofthe space occupied by the expandingluid.

Ordinarily the diaphragm-motor is in a collapsed condition, as shown in the drawings, being kept so either by the resistance ot' any machinery it is connected with or by springs or weights being provided for that purpose. l

The fluid which expands the apparatus enters through the inlet 12, and, passing through the passage in sleeve 7,fills the two shells and straightens the diaphragms, as shown in dotted lines in Fig. 1.' If there were nothing be* tween the diaphragms, they would merely straighten out, leaving` the shcllsin their position, but,having ring 3 placed between them, they are forced apart from either side of the ring in the same time. Thus the diaphragms become levers, ring 3 forming their pivot at the point where the former comes in contact with it, and the initial pressure of the entering fluid is increased by the additional power of said levers.

This apparatus may be used wherever high pressure is needed, and in its effects is very similar to a hydraulic press. It may be, in connection with appropriate machinery, used as a lifting-jack, propelling-motor, brake, and many other purposes. As a means to actuate the brake mechanism of railwaycars it is especially well adapted. In this case it may be secured by one of those sockets 13 to a stationary fixture on the car, while the other socket 13 takes the connection to the brakebeam. p

Several diaphragm-motors may be secured together, having a passage for the fluid from one to the other, thereby increasing the stroke or lift of the apparatus as many times as the number' of diaphragm-motors is increased.

I do not confine myself to any material to be usedthe diaphraginmay be leather, rubber, or metal (steeD-nor to the nature of the eXpanding-fluids,which may be water, oil, air, steam, or any other vapor.,`

Having thus explained my inventiomwhat I claim as new, and want to secure by Letters Patent, is as follows:

1. A diaphragm-motorconsisting of two dia phragms, 2 2, connected .centrallyandsecured to a sleeve, 7 8, or otherwise united in a suitable manner, having a loose ring, 3, between to keep them apart, secured by their outer edges to shells 1 1, one of them having an inlet, 12, and having a central orice through which the fluid fills the shells.

2. The combination of the following ele ments for the purposes described: two shells, 1 1, having initial sockets 13 13, or other equivalents, to connect them to and with the machinery in combination with Which they are to be used, one shell havingan inlet, 12, to admit the fluids, indentations 14; to increase the cubic capacity of the expanding uids, two flexible daphragms, 2 2, centrally connected with each other in a suitable manner, each 'diaphragm connected with its outer edge to one of the shells 1, a central passage in the diaphragms,whereby uids pass from one shell to the other, and a ring, 3, placed loosely between the diaphragms, which forms an abutment to the former when the apparatus is expanded.

3. The combination of such diaphragm-mo tors as above described with ring` 3 in series, whereby the lift or stroke of the Whole combined apparatus is multiplied as many times as the number of diaphragm-motors is increased.

In testimony of which invention I hereunto set my hand.
